As every year passes, the planet is getting warmer at a faster than normal rate. Harmful emissions exhausted by industries and vehicles increase the heat retention capacity of the atmosphere which is leading to a global climate change. Although it wasn’t noticeable until the past few years, it has been catching up with us now.

Untimely floods in coastal areas, droughts in central areas, cyclones, depleting ice caps and rising sea levels are all signs that the current energy trends need to be changed.

Most of us have an overwhelming fear of injections in our childhood days. For most of us, that fear does not subside as we grow up. Apart from creating a phobia, there are many disadvantages of injections with needles such as they cause tissue damage. They could also act as a source of infection if the needles are reused or used incorrectly. 

Needle free injections were first described by Marshall Lockhart in 1936 in his patent jet injection. By the early 1940’s high pressured guns were developed that used a fine jet of liquid to pierce the skin and deposit the drug under the tissue.

IoT, stands for Internet of things, term was first sprouted in the mind of Kevin Ashton at Auto-ID center at Massachusetts Institute of Technology in 1999. IoT is trending at very high pace in the scientist and researcher society. IoT alone holds a market potential of upto $14 trillion. By this fact we can assume what IoT hold inside for humanity. 

The IoT infrastructure consist of mainly 4 basic module: WSN or sensor Hub, wireless connectivity solution, cloud computing and storage solution and finally the user device Network. All these nodes can be PC or laptop, mobile device like phone or tablet or any other PDA or embedded computing device.
